4 Claims.

This invention appertains to new and useful improvements in vehicle wheel structures and more particularly to a wheel structure of the quick demountable type.

The principal object of the present invention is to provide a wheel structure which can be quickly demounted without requiring the removal of nuts from the usual wheel securing bolts.

Other objects and advantages of the invention will become apparent to the reader of the fol lowing specification.

In the drawings:

Figure 1 represents a fragmentary outside elevational view of the wheel,

Figure 2 is a fragmentary sectional view taken substantially on line 2-2 of Figure 1,

Figure 3 is a fragmentary sectional View taken substantially on line 3-3 of Figure 1,

Figure 4 is a fragmentary exploded View showing the parts in separated relation.

Referring to the drawings wherein like numerals designate like parts, it can be seen that numeral 5 representsthe axle of a vehicle rear end. The front axle will be somewhat different in construction as will the associated parts but the part contributing to the present invention will be identical.

Numeral 6 in Figures 2 and 3 represents the axle housing. Numeral 1 denotes a disk from which extends the cylindrical shell 8 in which the bearings 9 are located. The disk 1 is formed with a hub 2| for receiving the end of the axle 5 and nuts 1' hold the hub on the axle.

Stud-s l0 suitably anchored as at H in the disk 7 project beyond the outside face of the disk I. I

The numeral l2 indicates a stamped wheel disk and this as shown in Figure 4 is stamped out with a circular central opening l3 from which radiates the dove-tail shaped openings l4 and one edge portion of each of these dove-tail shaped openings I4 is provided with a notch l5, these notches receiving the threaded bolts 16 extending from' the aforementioned disk 1 and anchored thereto as at IT.

The wheel disk I2 is also provided with openings l8 equal in number to: the number of studs It! so that these studs are received in the openings [8 when the disk l2 has been rotated so that the notches l5 have received the bolts I6 and the wheel disk !2 has been forced inwardly against the disk 1.

Numeral l9 denotes the clamping plate which is provided with the dove-tail shaped projections 20 which radiate from the plate l9. This plate is provided with the central opening 2| for receiving the hub structure 2|.

Each of the dove-tail shaped projections 20 is provided with an opening 22 for receiving a threaded bolt [6. Nuts 23 are provided on these bolts, but are never removed as they are stopped by cotter pins or other suitable keys 24 before complete removal.

When the Wheel member [2 is to be removed, the nuts 23 are loosened so as to release the clamping action of plate 19 on the member I2 to permit the member 52 to be pulled forwardly out of engagement with the studs [0 and then said member 52 is given a partial turning movement to cause the notches l5 to move away from the bolts I6 and to place the openings [4 in register with the projections 20of plate I9 and then the member I2 is pulled forwardly to cause said projections 20 to pass through the openings l4 and thus the wheel member I2 is removed from the axle assembly.

As can be seen in Figure 2, a spring A is employed between the disk l and the plate l9, this spring being wholly confined within the central opening E3 of the wheel l2 when the nuts 23 are holding the plate l9 against the wheel l2. The purpose of this spring A is to automatically force the plate l9 outwardly so that the wheel l2 can be readily disengaged from the studs l0 without any inconvenience on the part of the workman.

Having described the invention what is claimed as new is:

1. A wheel structure comprising a plate having a plurality of threaded members extending therefrom, a wheel structure having its central portion formed with an opening, said wheel structure being formed with adjacent openings radiating from the central opening, said wheel structure being formed with notches in the edge portions of the said additional openings to receive the threaded bolts, and nuts on the bolts.

2. A wheel structure comprising a plate having a plurality of threaded members extending therefrom, a wheel structure having its central portion formed with an opening, said wheel structure being formed with adjacent openings radiating from the central opening, said wheel structure being formed with notches in the edge portions of the said additional openings to receive the threaded bolts, nuts on the bolts, and stop means on the outer ends of the bolts to prevent complete displacement of the nuts from the bolts.

3. A wheel structure comprising a plate having a plurality of threaded members extending therefrom, a wheel structure having its central portion formed with an opening, said wheel structure being formed with adjacent openings radiating from the central opening, said wheel structure being formed with notches in the edge portions of the said additional openings to receive the threaded bolts, nuts on the bolts, a clamping plate provided with radially extending projections each formed with an opening for receiving a bolt.

4. A wheel structure comprising a plate having a plurality of threaded members extending therefrom, a wheel structure having its central portion
